Ignoring the theft implications of starting your car from a mile away, the Directed Electronic starters seem pretty useful if you're in need of that much range. Coming in three deadly-sounding flavors, Python, Viper and Clifford, thestarters have a display on it to notify you whether your hood, door, or trunk is open.

Useful for city dwellers who park far away but want to heat up their cars on cold winter mornings, these starters will be available in August starting at $550. – Jason Chen
